Extremity Function After Transfemoral Transcatheter Aortic Valve Implantation: A TAVI XS Sub‐Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Physical decline after transcatheter aortic valve implantation (TAVI) is associated with worse outcomes. However, data on post‐TAVI extremity function are limited. This sub‐study of the TAVI XS trial aimed to assess extremity function after transfemoral TAVI, evaluate functional decline, compare outcomes between upper‐and lower ...

Organophotoredox/Cobalt‐Catalyzed Retro‐Hydroformylation of Aldehydes

open access: yesChemistryEurope, EarlyView.
A new photoredox/cobalt retro‐hydroformylation is developed. This one‐pot two‐step process involves the in situ formation of the corresponding 1,4‐dihydropyridine as key intermediate. Under mild reaction conditions, alkenes are efficiently produced from a wide range of aliphatic α‐monosubstituted aldehydes, with high functional‐group tolerance.

Bottom‐up Strategies for Generating Polymer Protocells That Mimic Cellular Communication

open access: yesChemistry – A European Journal, EarlyView.
This review focuses on polymeric protocells produced using a bottom‐up approach. Polymer‐based assemblies guarantee stability and designability by adjusting the properties of the amphiphilic copolymers used. The review covers protocell architectures, production, and their intra‐ and intercellular communication mechanisms.
